Still need turbo ideas...

[S13 240SX]

I got this off ka-t.org....

Mild power adder, say you want around 200 rwhp.

Turbo Manifold Blow Off Valve Small Intercooler (potentially get away with a side mount) Turbo T25/T28/14B, etc. Smaller T2 setups. Usually will be internally wastegated. Downpipe 2.5" is perfectly fine Replacing the Exhaust is starting to be very necessary at this stage, so I would start to shop for that as well.

Fuel Control DSM 450cc Injectors Apexi SAFC2 Greddy Emanage Back off base timing at distributor or MSD BTM

But my questions is how can I get at least 230rwhp, cuz it says its for 200rrwhp, but 200 is not enough for me.... what parts can i use for 230rwhp setup at 8psi?

I have a mainfold picked up, i'm gonna order the kit off jgstools.com for 179 dollars, but a turbo I have no idea what to use yet? help me out to get my 230rwhp, 8 psi goal? as for torque I don't even care what the number comes out to be, right now i'm just wanting an 8psi setup with 230rwhp.and I have no idea if dsm injectors will be good enough because I really don't those cuz then I gotta buy and wiring whatever they are called, and i don't wanna do that, for for my fuel pump I wondering If I could kepe stock because my fuelpump is stripped out anyways and none of the nuts turn losoe.

[sunnys14]

you are gonna need a t3/t4 turbo, walbro fuel pump, 370cc injectors & safc2 to control injectors to get atleast 230whp @ 8 psi. with a t25 you are going to need to push atleast 14 psi to get 230whp on a KA. also with a t25, power will drop off around 5k rpms due to the t25 being pushed too hard.

[S13 240SX]

okay will a T3 off off a saab, volvo, or 300zx work just the same for me as a T3/T4. I can go to the junkyard then and look for some t3's off those few cars.I have a ka24e with 90k mileage btw.

[sunnys14]

NO, a t3 off a 300zx will not work the same. with that turbo you will have to push atleast 10psi to make it work as much as a t3/t4 hybrid. the good thing about a t3 off a 300zx is you will have better boost response.

[S13 240SX]

so I"m gonna most likey need to hall out the cash for a t3/t4 hybrid to get my goals?

[nissanfanatic]

I bet a T3+a good manifold/downpipe+a tuned ECU will get you 230whp at 8psi...

[sunnys14]

thats gonna cost more to do than getting a t04e, revhard mani, 3" downpipe, 370cc, and safc2. or if u wanna go the cheap route, ditch the 370cc and safc2 and get a 10:1 fmu. that should get you 230ish whp @8psi

[S13 240SX]

well i'm gonna get a manifold off jgstools.com the 179 dollar kit mainfold, a downpipe im gonna go with a 2'5. and my ecu i may just do that, i may not get an safc2... cuz i have 3 ecu's and i may tune my own ecu to control my fuel system. what ya guys think about doing it that way? Plus my 240 has major weight reductions, and stripped a/c system, no clutch fan, and 300ZX TT fuel fitler.

[sunnys14]

how are you going to tune your own ECU? its better that you should get 370ccs or better if you are going to start boosting. stock injectors can boost for a lil while, but who knows when they will give out. stripped AC, no clutch fan, and 300zx fuel filter wont give you much HP... more like 5hp at the crank.

[S13 240SX]

I"m not sure about the ecu thing yet.. I been reading a few forums.. so far i need a chip burner and a socket to do it.

[Iamjohnhayes]

well the removal of those helps as you add more hp to the engine, plus when you remove the weight from your car you don't need to have as much hp to move as fast (yes i know its not that huge if a difference till you are talking 100's of pounds)

[nissanfanatic]

I was saying an ECU tune. Might be expensive, but that+say 550cc Deatschwerks+Z32 and its out of the way for up to 400whp. Or just tune for 370cc and stock MAFS for a ready-to-beat everyday setup. You figure $600, but at least you don't ever have to tune, its reliable, and its plug and play.

No duh, its gonna be more expensive... But sometimes you have to pay for power... From expirience, its better to just get the good stuff the first time... I have spent so much money trying to take shortcuts that I prolly could have bought two of my current setups by now.... Learn from my mistakes.

[S13 240SX]

nah if i do an ecu tune i'll do it myself i have 3 ecu's so i got a few to learn on first and plus its much cheaper if i do my own ecu.

[hannibal]

No problem tune your own. A Z31 T3 can do 230whp without too much stress (about 10psi). The catch is you will have to run more than your set limit of 8psi. Only a T3/T4 (or similarly sized turbo) can make that power at that level of boost.

If you know you want 230whp, I'd rather skimp on the turbo and manifold than use an FMU. I recommend:Z31 T3 (0.60AR 60trim comp, 0.63AR turbine)JGS log mani370cc from SR (or Deatschwerks??)Bikirom ECU1g DSM BOVWalbro 255 (under $100 on Ebay)

Two issues: the internal wastegate on the Z31 is set at 6-7psi so you'll need a boost controller and your tune-it-yourself ECU wont be as reliable as a plug and play Enthalpy or JWT, but it'll save you some bucks.

fanatic and sunny both have running KA-Ts, and I dont. But thats my 2 cents....

[nissanfanatic]

the self tune ECU can be just as reliable as a JWT or an Enthalpy.. It will take a while for you to get the hang of it and figure out a good tune tho.

[S13 240SX]

Iwannas15, you make a lot sense to me from some reason. : )

so yeah I want 230whp and torque I don't know I haven't really thought about it yet, I guess just whatever it turns out to then i"ll get it dynoed.

So then my new list in parts to search for will be.. the following..

FMU. I recommend: I can't really afford a safc2 so ccan't i just tune my ecu to control my fuel?Z31 T3 (0.60AR 60trim comp, 0.63AR turbine)JGS log mani - YEP i'm gonna order the kit for 179 dollars with a t3 flange.370cc from SR - I have a single ka, sr injectors are side-feeded and i need top feeded, so i will go with the 370cc's from the CA18DETBikirom ECU - again, I wanna learn to tune an ecu to control the fuel injectors I install... 1g DSM BOV - that's good I already have a DSM Boosch BOV that can handle 300HP.Walbro 255

I can pretty much afforable the parts and turbo, but ECU and safc2 I can not, so that's why I wanna get into trying to tune my own ecu's for like much cheaper, and I wanna be able to have my ecu tune to read all the fuel upgrades I use, if you have any idea's on how easily I can do that, Please IM me, my s/n is in my profile on here.

[S13 240SX]

wait.... I don't think the 300zx turbo is that big when you said it is a Z31 T3 (0.60AR 60trim comp, 0.63AR turbine) that can't be the stock turbo size, it's a t3 but is the AR, trim and turbine really that large? that didn't make sense... Please find me one, I search ebay and got nothing on any 300ZX turbo.

[S13 240SX]

I found a bigger better turbo... its a Holset HX35W how great will that turbo be if boosting it at only 8psi for on my single cam ka?

[emperor_lunchbox]

It seems to me that people have laid down the advice you asked for. You obviously feel that you dont know exactly what to get and the fine people of this forum developed a laundry list for you. My advice is to take their advice and get the Z31 if you cannot afford the T3/T4 and get the rest of the approved parts.

I used to do the same thing, I would ask for help when not clear and when the answer I got didn't match what I thought I disreguarded the advice, and I am currently $700 into my rebuild.TAKE THE ADVICE.

i know i would take their advice and get the stock turbo off a stock z31 but the problem is those years were what 84 to 86 model??? i can't not find any in the junkyard and there are none up for bid on ebay, so looks like i need to look into a turbo where I can easily get off ebay for cheap like a Turbo..... Holset HX35W like that turbo, becasue those go for real cheap on ebay like all the time.

[emperor_lunchbox]

try turbocalculator.comI dont know anything about their company or if they have a good rating or not, but I do know they have inexpensive turbos.You can also try cheapturbo.com

I think those are the URL'sIf they dont work email me and I will check my laptop favorites.my email is [email protected]

I found a T3/T04E on turbocalculator.com for $399 (I think).There is alot of options there too.

[nissanfanatic]

turbocalculator stuff is trash. Cheap turbos that fall apart.

[S13 240SX]

yeah I checked these two links out and the prices are not cheap, thats way too much money, I only wanna spend no more than 200 bucks on a turbo..

[nissanfanatic]

HA...

Wait and turbo your car in a year or so... Limiting yourself to $200 for a turbo only makes me wonder what you plan on spending on timing/fuel control....

Save up some money and try again later.

[S13 240SX]

no ihave the money for fuel control, timing i'm just gonna retard it some. I just wanna spend 200 bucks on a turbo to save for my down-pipe and full exhuast.

[emperor_lunchbox]

well, I have never purchased anything from either of their sites, I just know they are "cheap".Apparently, S13 240SX is cheaper.... j/k "cheap" shot... Man I am full of 'em.Anyway, S13 it seems like you have your goals in order, but you will definately need to spend more than 2 bills on a turbo. You will have to spend more than that to get one that will actually work with no shaft play or one with good specs. Correct me if I am wrong but isn't the turbo the most important part of a turbo system....bottom line, you need to spend more on the turbo.

[S13 240SX]

I found a turbo and I may call the dude and ask him if i can come down and pick it up without paying for shipping... its a sr20 t25 turbo.

[K240]

That turbo would be fine, but for LOW boost applications only.

[pr240sx]

use the 450cc injectors and a SAFCBack down your timming to at least 15 degreesuse a good intercoolerGet that z31 turbo, use it at 8 psi and check for power, if need more, upgrade the compressor part of the turbo to a T4.

Remember Cheap - Fast - Reliableyou can only choose 2!

[Skidmark]

Hmmm, T25 @ 8psi? Get ready for sub-200whp numbers, dude. I would also recommend that you A.) keep searching for a Z31 turbo or B.) bite the price bullet and buy the T3/T4. Nothing else that close to your price range will do what you want. The T3 will support your goals with headroom at higher boost, but honestly a brand new T3/T4 isn't that much more expensive than a rebuilt T3 and will give you WAY more headroom. Quite fighting it and just buy it
